Hi all,

I have some questions while using mmwave studio with hardware AWR1642BOOST and DCA1000EVM to analyze the data using objects from "Test Source" tab

here are my configs:

"Connection" tab

"StaticConfig" tab

"DataConfig" tab

"SensorConfig" tab

and here are my questions:

1.While setting only 1 object in "TestSource" tab, in the PostProc figure I got 1 object at the "Detection & Angle estimation Results" subplot and 1 peak at the "1D FFT amplitude profile" subplot

but I got 2 peaks at the "2D FFT amplitude profile" subplot

I wonder why would this happen? i only have 1 range and 1 speed but i got 2 peaks at the 2D FFT plot with same range but different speed

this is my "TestSource" object settings

and here are the "PostProc" figure results

2.The second question is kinda like the one above, while I set 2 objects in the "TestSource" tab I will get results of lots of objects from the "PostProc" figure

not only the "2D FFT amplitude profile" subplot but also "1D FFT amplitude profile" and "Detection & Angle estimation Results" subplots as well

in this case I got 4 objects on my "Detection & Angle estimation Results" subplot and more on the "1D FFT" and "2D FFT" results

this is my "TestSource" object settings

and here are the "PostProc" figure results

please help me figure out why would this happen while i haven't even record real objects with noises, or are there any steps i have done wrong

best regards
